The start: 0 to 100 km/h

Off the line, the M240i hits 100 km/h in 4.67 s versus 8.92 s for the 218d xDrive. At this point, the M240i leads by 4.26 s and sits roughly 28 m ahead.

From 100 km/h to 400 metres

At 200 metres, the M240i is doing 147 km/h against 113 km/h for the 218d xDrive. The gap is 2.58 s. The challenger starts to claw back ground.

At 400 metres standing start, the M240i crosses the line in 12.78 s versus 16.67 s. The 3.89 s gap represents roughly 143 m of track - a gap visible to the naked eye.

Beyond 400 metres: top speed comes into play

Past 400 metres, the M240i continues to build its lead. At 600 metres, it runs at 205 km/h versus 157 km/h. At 1,000 metres, the M240i finishes in 23.03 s versus 30.09 s, with a 7.05 s lead.

What the numbers don’t tell you

Both rivals are electronically governed, but not at the same level: the M240i is capped at 250 (i.e. 155 mph - industry threshold) km/h, the 218d xDrive at 209 km/h. This isn’t a physical engine limit - it’s a manufacturer choice, usually for tyre safety or homologation reasons. Neither car reaches its true aerodynamic top speed.

With two combustion powertrains, the difference comes down to power-to-weight ratio (4.49 kg/hp vs 10.13 kg/hp) and transmission (Automatic vs Automatic).

In European road use (130 km/h max), both vehicles reach the legal speed limit in under 14.27 seconds. The 4.26 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
